I have been meaning to comment on the use of the term "vegetable oil." All it means is that it is not from an animal source, yet people use it as though it means something specific. I believe that if you see it on a label, it is an indicator that inferior oils are being used.
pauljoseph, you can probably find rapeseed oil. Is that something you might use? Canola oil is bred from rapeseed (the word is for Canadian Oil), to eliminate erusic acid. Currently there is concern that the seed has been genetically modified, so I try to stick to non-GMO sources.
And then, some people use olive oil.
